Contract #3: Black River Street and Dunkley Infrastructure Project

Contract #3: Black River Street and Dunkley Infrastructure Project

SUMMARY OF PROJECT

This project involves sanitary sewer reconfiguration to serve the new Main Lift Station at the South Haven Waste Water Treatment Plant (WWTP):

On Black River Street, from Dyckman Avenue to Wells Street, new sanitary sewer will be placed at the roadway centerline, the roadway will be reconstructed (including new curb and gutter) and widened to allow for additional on-street parking, sidewalk will be constructed on the east side of the roadway, and a new lift station will be placed on the west side of the road roughly halfway between North Street and Wells Street. This lift station will have a force main directionally drilled under the Black River and its flow directed to the new Main Lift Station. The existing sanitary sewer currently located at the River’s edge will be removed where possible or abandoned in place. Sanitary services will be rerouted to the new sanitary main within the roadway.

On Dunkley Avenue, sanitary sewer will be installed around the WWTP to the east and the north following the existing fence line to connect the existing sanitary flow from the Wells Street Lift Station which is planned to be abandoned. New sanitary sewer will be installed following the existing roadway alignment to the south to allow flows coming from Dyckman Avenue to be conveyed by gravity rather than pumped by the existing Main Lift Station. The roadway will be reconstructed including curb and gutter improvements, and shoulder upgrades within Black River Park. The parking lot just inside the park will be reconfigured, and water main will be extended from just before the drainage ditch to past the WWTP.
